I'm at the stage where I'm about to start the initial PCB design, however I would like to get an idea of housing etc, as the type switches, external connectors and the general asthetics need to be taken into account so I can use the right footprints etc.

This is where I lack the expertise as most of my projects don't end up in housings.

Is anyone with 3D modeling experience willing to come up with some housing ideas?
